    Health Benefits of Grapes for Hamsters

    Good source of vitamins and minerals

    Grapes contain several vitamins and minerals which are essential for your hamster’s health.

      Vitamin C

    For starters, grapes provide a healthy dose of vitamin C. This is crucial in ensuring these furballs have a strong immune system. 

    The lack of Vitamin C may cause scurvy, a condition that can lead to paralysis of their back legs in severe cases. sbobet

      Vitamin K

    This fruit is also a good source of vitamin K, a vitamin that aids blood clotting and helps to strengthen your hamster’s bones.

      Vitamin B6

    In addition to Vitamin C and K, grapes also have small amounts of Vitamin B6. This is useful in helping these creatures combat stress and hence, maintain their nervous system and energy levels.

      Other minerals

    This fruit can also supply your pet with other useful minerals such as calcium and iron. The former helps to boost immunity and maintain healthy bones while the latter improves heart health.

    Good source of antioxidants

    Grapes contain a substance named resveratrol, which is a powerful antioxidant. This along with other antioxidants can help to boost hamsters’ immune systems. 

    Antioxidants also help your pet fight against viral and fungal diseases, making them essential for overall health.

    Health Risks of Grapes for Hamsters

    Digestive issues

    Grapes are high in fructose, a natural sugar that can cause gas.

    They also contain high concentrations of tannins, which can cause stomach upset if consumed in large quantities. Hamsters may be prone to diarrhoea as a result of their sensitive digestive systems.


    Dr. Maureen (from Petkeen) has shared that excessive grape consumption can cause hamsters to gain unhealthy weight and develop diabetes. Thus, it’s important to control their sugar intake.

    Campbell’s and Chinese hamsters face a higher risk of developing diabetes. If you own these breeds, you may want to seek advice from a vet before feeding them grapes as a snack.

    How to Feed Grapes to Hamsters?

    Hamsters may have a preference for their fruits. Therefore, it’s recommended to do a taste test before including grapes in their diet. 

    Here are some pointers you should note if you’d like to try feeding grapes to your pet. 

    How many grapes can hamsters eat?

    According to Sherry (from Petsolino), the amount of grapes that you can feed to your hamster depends on their breed.


    Syrian hamsters are the largest breed and therefore, can generally consume more grapes than other breeds. You can give them 1 grape per week.


    Roborovskis are the second largest breed, implying that they can consume more than other breeds but less than that of a Syrian. 1/2 a grape per week would be an appropriate amount.

      Chinese, Campbell’s and Winter White

    These breeds are dwarf hamsters, which means that they have a much smaller appetite. You can consider serving approximately ⅙ of a grape per month as an occasional treat.

    How to feed grapes to hamsters

    It’s important to introduce new foods, including grapes, slowly and in small bite-sized portions.

      Step 1: Wash the grapes

    To remove any traces of pesticides or harmful chemicals, thoroughly wash the grape’s exterior with warm water. It’s also advised to peel the skin off for safer consumption.

      Step 2: Slice the grapes

    Cut the grape into quarters down the centre, exposing the seeds.

      Step 3: Remove the seeds

    Gently remove the seeds from the centre part of the grape before serving the treat to your pet. This will prevent your hamster from choking.

    Monitor your hamster’s behaviour to ensure that they aren’t having an allergic reaction or a stomach upset. Things to look out for include
    • Lack of energy – this could indicate that they’re having difficulty digesting the new food
    • Lack of appetite – if they aren’t interested in eating their usual foods, it could also be a sign that grapes aren’t a good fit for their diet
    • Loose stools or diarrhoea
    If any of these symptoms persist for more than 48 hours, please contact your vet for a thorough health check.
